DJ Boy (c)1989 Kaneko
Hardware has many similarities to Air Buster.
Self Test has two parts:
1) color test : press button#3 to advance past color pattern
2) i/o and sound test: use buttons 1,2,3 to select and play sound/music
- CPU0 manages sprites, which are also used to display text
irq (0x10) - timing/watchdog
irq (0x30) - processes sprites
nmi: wakes up this CPU
- CPU1 manages the protection device, palette, and tilemap(s)
nmi: resets this CPU
irq: game update
- CPU2 manages sound chips
irq: update music
nmi: handle sound command
- The "BEAST" protection device has access to DIP switches and player inputs.
